When the historical monitoring information is the image information, the features of the image information (for example, the color and height of vegetation, etc.) may be extracted to determine the historical image feature vector of the greenspace within the historical time period. Each dimension of the historical image feature vector may correspond to one image feature. The first feature extraction layer may be a convolutional neural network model.

The label may be obtained by manually labeling sample monitoring information of the sample greenspace within the sample time period. It should be understood that the vegetation types of the sample greenspace and the greenspace to be predicted should be the same or the same category, for example, the vegetation types of the sample greenspace and the greenspace to be predicted are both ryegrasses. Multiple training samples are input into an initial first feature extraction layer, and the output of the initial first feature extraction layer is input to an initial score determination layer. A loss function is constructed based on the output of the initial score determination layer and labels. The parameters of the initial first feature extraction layer and the initial score determination layer are iteratively updated based on the loss function, until the preset conditions are met, and the training ends. The parameters of the first feature extraction layer and the score determination layer may be determined to obtain a trained image recognition model. Preset conditions may include, but are not limited to, a loss function converging, a loss function value being less than a preset value, or a number of training iterations reaching a threshold, etc.

In some embodiments of the present disclosure, the historical growth information of the each greenspace within a historical time period may be determined through the image recognition model, thereby reducing the cost of manual judgment and improving processing efficiency. In still other embodiments of the present disclosure, different data may be processed through a multi-layer structure of the image recognition model, thereby further improving an accuracy of calculation result of the image recognition model.

Step 510, for each greenspace, the urban management platform obtains the historical irrigation parameters of the greenspace within the historical time period through the irrigation object platform and obtains the historical environment information of the greenspace within the historical time period through the urban monitoring object platform.

The historical irrigation parameters refer to the irrigation parameters of the greenspace within the historical time period. Merely by way of example, the historical irrigation parameters may be irrigation parameters of a greenspace irrigated in a previous month. The historical irrigation parameters include: the irrigation frequency being 3 days/time, and the average irrigation water amount per time is 9-10 tons/mu. In some embodiments, the historical irrigation parameters may be a sequence based on time, and the sequence may include the irrigation parameters at a plurality of time points within the historical time period.

The historical irrigation parameters may be obtained through the irrigation object platform. For example, the urban management platform may obtain the historical irrigation parameters from historical data of the irrigation object platform.

The historical growth information, historical irrigation parameters, and historical environmental information may be sequences based on time. The output of the growth condition prediction model may include the first growth information of the greenspace within the historical time period.

In some embodiments, the growth condition prediction model may be obtained by training. An initial growth condition prediction model may be trained based on a plurality sets of labeled training samples.

The label may be the growth information of the sample greenspace within a second sample time period, and the first sample time period is earlier than the second sample time period. The label may be obtained by manually labeling the sample monitoring information of the sample greenspace within the second sample time period, or by processing the sample monitoring information through an aforementioned image recognition model. It should be understood that the vegetation types of the sample greenspace and the greenspace to be predicted should be the same or of the same category. A plurality of training samples are input into the initial growth condition prediction model. The loss function is constructed based on the output of the initial growth condition prediction model and labels, and the parameters of the initial growth condition prediction model are iteratively updated based on the loss function. When the trained model satisfies the preset conditions, the training ends, and the trained growth condition prediction model is obtained. The preset conditions may include, but are not limited to, the loss function converging, the loss function value being less than the preset value, or the number of training iterations reaching the threshold, etc.

In some embodiments, the growth condition prediction model may further be a custom model. As shown in FIG. 6 , the growth condition prediction model 650 may include a second feature extraction layer 650-1, a third feature extraction layer 650-2, a fourth feature extraction layer 650-3, and a growth prediction layer 650-4.

The growth sequence feature may refer to an obtained sequence feature after performing a feature extraction on the historical growth information.

In some embodiments, a third feature extraction layer may process the historical irrigation parameters to determine an irrigation sequence feature of the greenspace within the historical time period. The third feature extraction layer may be the deep neural network model. As shown in FIG. 6 , an input of the third feature extraction layer 650-2 may be historical irrigation parameters 620, and an output of the third feature extraction layer 650-2 may be an irrigation sequence feature 652. The irrigation sequence feature may refer to the obtained sequence feature after performing a feature extraction to the historical irrigation parameters.

In some embodiments, a fourth feature extraction layer may process the historical environment information to determine an environment sequence feature of the greenspace within the historical time period.

The training sample includes sample growth information, sample irrigation parameters, and sample environment information of the sample greenspace within a third sample time period. The label may be the growth information of the sample greenspace within a fourth sample time period, and the third sample time period is earlier than the fourth sample time period. The label may be obtained by manually labeling the sample monitoring information of the sample greenspace within the sample time period. It should be understood that the vegetation types of the sample greenspace and the greenspace to be predicted should be the same or of the same category, for example, the vegetation types of the sample greenspace and the greenspace to be predicted are both ryegrasses. The sample growth information of the training sample is input into an initial second feature extraction layer, the sample irrigation parameters of the training sample is input into an initial third feature extraction layer, and the sample environment information of the training samples is input into the initial fourth feature extraction layer. Then, the outputs of the initial second feature extraction layer, the initial third feature extraction layer, and the initial fourth feature extraction layer are input into the initial growth prediction layer, and the loss function is constructed based on the output of the initial growth prediction layer and labels. The parameters of each layer of an initial growth condition prediction model are iteratively updated based on the loss function until the preset conditions are met, and the trained growth condition prediction model is obtained. The preset conditions may include, but are not limited to, the loss function converging, the loss function value being less than a preset value, or the number of training iterations reaching a threshold, etc.

As shown in FIG. 6 , a growth condition prediction model 650 may further include a first feature extraction layer 650-5.

In some embodiments, the first feature extraction layer may process the historical monitoring information to determine the historical image feature vectors of the plurality of greenspaces. As shown in FIG. 6 , an input of the first feature extraction layer 650-5 may be historical monitoring information 640, and an output of the first feature extraction layer 650-5 may be a historical image feature vector 654.

In some embodiments, the parameters of the first feature extraction layer may be obtained by performing transfer learning on the first feature extraction layer in a trained image recognition model. Descriptions regarding the image recognition model may be found in FIG. 4 and its relevant descriptions.

Step 530, the urban management platform determines the target irrigation parameters of the each greenspace within the first future time period based on the first growth information corresponding to the each greenspace.

In some embodiments, it may perform modeling or use the plurality of data analysis algorithms, such as regression analysis, discriminant analysis, etc., to analyze and process the historical growth information to obtain the target irrigation parameters of the each greenspace within the first future time period.

In some embodiments, the urban management platform may obtain a preset total amount of irrigation in the target area within the first future time period, and may determine the target irrigation parameters corresponding to the each greenspace combined with a preset algorithm based on the preset total amount of irrigation and the first growth information of the each greenspace. More descriptions regarding the above-mentioned embodiments may be found in FIG. 7 and its relevant descriptions thereof.

In some embodiments, the urban management platform may further obtain the preset total amount of irrigation in the target area within the first future time period, may determine a plurality of candidate irrigation schemes of the plurality of greenspaces based on the preset total amount of irrigation and the first growth information corresponding to the each greenspace, and each candidate irrigation scheme includes a set of candidate irrigation parameters for irrigating the each greenspace. The urban management platform may determine the target environment information of the each greenspace within a second future time period. For the each candidate irrigation scheme, after irrigating the plurality of greenspaces based on the candidate irrigation scheme, the urban management platform may determine second growth information of the each greenspace within the second future time period through the growth condition prediction model based on the candidate irrigation scheme, the target environment information, and the first growth information. The urban management platform may determine a growth promotion value corresponding to the candidate irrigation scheme based on the second growth information of the each greenspace. The urban management platform may determine a target irrigation schemes of the plurality of greenspaces based on the growth promotion value corresponding to the each candidate irrigation scheme, and the target irrigation scheme includes the set of target irrigation parameters for irrigating the each greenspace within the first future time period. More descriptions regarding the above-mentioned embodiments may be found in FIG. 9 and its relevant descriptions thereof.

Some embodiments of the present disclosure may accurately predict the growth condition of the greenspace through a model based on historical data of greenspace. In this way, more scientific target irrigation parameters may be determined, and irrigation water resources and human resources responsible for irrigation may be saved under the condition of ensuring a normal growth of the greenspace.

FIG. 7 is an exemplary flowchart for determining target irrigation parameters according to some embodiments of the present disclosure. As shown in FIG. 7 , a process 700 may include the following steps.

Step 710, the urban management platform obtains the preset total amount of irrigation in the target area within the first future time period.

The preset total amount of irrigation refers to the total amount of water available for irrigation in the target area within the first future time period.

The preset total amount of irrigation may be obtained from a database of the urban management platform. For example, The preset total amount of irrigation in the database of the urban management platform may be updated periodically (e.g., daily, weekly, etc.) according to known conditions. When there is a data request for obtaining the preset total amount of irrigation, the latest preset total amount of irrigation may be retrieved for subsequent processing.

Step 720, the urban management platform determines the target irrigation parameters corresponding to the each greenspace combined with the preset algorithm based on the preset total amount of irrigation and the first growth information of the each greenspace.

In some embodiments, the urban management platform may use the plurality of preset algorithms to analyze and process the preset total amount of irrigation and the first growth information of the each greenspace to determine the target irrigation parameters corresponding to the each greenspace. For example, the preset algorithms may include the regression analysis, discriminant analysis, etc.

In some embodiments, the urban management platform may determine the plurality of candidate irrigation schemes of the plurality of greenspaces based on the preset total amount of irrigation and the first growth information corresponding to the each greenspace, and each candidate irrigation scheme includes a set of candidate irrigation parameters for irrigating the each greenspace. For each candidate irrigation scheme, the urban management platform performs at least one round of iterative updation on the candidate irrigation scheme through the preset algorithm to determine the growth promotion value of the candidate irrigation scheme within the second future time period. The urban management platform determines the target irrigation scheme of the plurality of greenspaces based on the growth promotion value corresponding to the each candidate irrigation scheme, and the target irrigation scheme includes a set of target irrigation parameters for irrigating the each greenspace within the first future time period. More descriptions regarding the above-mentioned embodiments may be found in FIG. 8 and its relevant descriptions.

Some embodiments of the present disclosure may perform a more scientific distribution of the planned preset total amount of irrigation water based on the preset total amount of irrigation and the first growth information of the each greenspace.

FIG. 8 is another exemplary flowchart for determining target irrigation parameters according to some embodiments of the present disclosure. As shown in FIG. 8 , a process 800 may include the following steps.

Step 810, the urban management platform determines the plurality of candidate irrigation schemes of the plurality of greenspaces based on the preset total amount of irrigation and the first growth information corresponding to the each greenspace, and the each candidate irrigation scheme includes a set of candidate irrigation parameters for irrigating the each greenspace.

The candidate irrigation scheme may refer to a candidate scheme for irrigating the plurality of greenspaces in the target area. The candidate irrigation scheme may include the candidate irrigation parameters of the each greenspace. It should be understood that the total amount of water used by the candidate irrigation parameters of each greenspace of the each candidate irrigation scheme should not exceed the preset total amount of irrigation. The candidate irrigation parameters may refer to the irrigation parameters distributed to each greenspace in the target area in the candidate irrigation scheme. For example, a first irrigation parameter of a greenspace may include an irrigation water amount of 2 tons/mu.

In some embodiments, the urban management platform may perform analysis and processing on the preset total amount of irrigation and the first growth information corresponding to the each greenspace to determine a plurality of candidate irrigation schemes. For example, the preset total amount of irrigation may be distributed based on an area ratio of the each greenspace, and an initial irrigation water amount of the each greenspace may be determined. The irrigation water amount is adjusted based on the plurality of adjustment values corresponding to the first growth information of the each greenspace, and the irrigation water amount of the each greenspace is determined. Then, a plurality of candidate irrigation parameters of each greenspace is determined based on the irrigation water amount of the each greenspace and preset irrigation rules of the each greenspace. For example, based on the area of a greenspace, it is preliminarily determined that the initial irrigation water amount of the greenspace in the next three days is 2 tons. The first growth information of the greenspace is 85 points, and according to the preset correspondence, it may be determined that the adjustment values corresponding to the first growth information are −0.10 tons, −0.15 tons, and −0.20 tons. Based on the irrigation water amount of the greenspace in the next three days being 1.90 tons, 1.85 tons, and 1.80 tons respectively, the irrigation water amount is distributed according to the irrigation rules of the greenspace to determine the plurality of candidate irrigation parameters of the greenspace. In some embodiments, the plurality of candidate irrigation parameters of each greenspace may be combined to determine multiple candidate irrigation schemes.

As another example, the urban management platform may determine, based on the historical data, the historical irrigation scheme corresponding to the time period in which the each greenspace is similar to the preset total amount of irrigation and the first growth information corresponding to each greenspace, and take the aforementioned historical irrigation scheme as a candidate irrigation scheme.

Step 820, the urban management platform performs at least one round of iterative updation on the plurality of candidate irrigation schemes through the preset algorithm until satisfying the preset conditions, the plurality of candidate irrigation schemes after iteratively updating converge to the target irrigation scheme, and the target irrigation scheme includes a set of target irrigation parameters for irrigating the each greenspace within the first future time period.

In some embodiments, the urban management platform may perform the at least one round of iterative updation on the each candidate irrigation scheme through the preset algorithm. For each iteratively updated candidate irrigation scheme, the growth promotion value corresponding to the iteratively updated candidate irrigation scheme is determined based on the iteratively updated candidate irrigation scheme. The growth promotion value may represent overall growth information of all greenspaces within the second future time period. The growth promotion value may be determined based on the second growth information, representing the sum of the second growth scores. The second growth information may represent the growth information of the greenspace within the second future time period. Similar to the historical growth information, the second growth information may be represented through the second growth score. For example, the second growth score may be a value of 0-100. In some embodiments, the iteratively updated candidate irrigation scheme may be processed based on the growth condition prediction model to determine the growth promotion value corresponding to the iteratively updated candidate irrigation scheme. More descriptions regarding the determining the growth promotion value corresponding to the iteratively updated candidate irrigation scheme may be found in FIG. 9 and its relevant descriptions thereof.

For each candidate irrigation scheme, during a process of iteratively updating the candidate irrigation scheme, the candidate irrigation parameters of the candidate irrigation scheme may correspond to a multi-dimensional increment. The multi-dimensional increment may refer to an adjustment range of the irrigation water amount of each greenspace included in the candidate irrigation scheme in each iteration.

In the first round of iteration, the initial candidate irrigation scheme may be updated based on an initial multi-dimensional increment to obtain the updated candidate irrigation scheme. The updated candidate irrigation scheme is determined as the candidate irrigation scheme to be processed, and the initial multi-dimensional increment is determined as a multi-dimensional increment to be processed in the next round. The initial multi-dimensional increment may be a system default value, experience value, artificial preset value, etc., or any combination thereof, which is set according to actual requirements.

In some embodiments, the initial candidate irrigation scheme may be obtained by initializing vectors. An exemplary process for initializing vectors is as follows: for several greenspaces (assuming the number of greenspaces is D), the number of initial candidate irrigation schemes may be set as N, meanwhile, the dimension of the each initial candidate irrigation scheme is D (each dimension corresponds to the irrigation water amount of a greenspace), a vector X_(i) ⁰ corresponding to the i^(th) initial candidate irrigation scheme may be denoted as: (X _(i1) ⁰ ,X _(i2) ⁰ , . . . ,X _(iD) ⁰), the vector corresponding to the N initial candidate irrigation schemes may be denoted as: (X ₁₁ ⁰ ,X ₁₂ ⁰ , . . . ,X _(1D) ⁰),(X ₂₁ ⁰ ,X ₂₂ ⁰ , . . . ,X _(2D) ⁰), . . . ,(X _(N1) ⁰ ,X _(N2) ⁰ , . . . ,X _(ND) ⁰)). where 0 is the identifier (representing the 0^(th) round of iteration, i.e., an initial value that has not yet started the iteration), i is the number of the candidate irrigation scheme, i≤N.

In each subsequent round of iteration, the multi-dimensional increment to be processed of the round is updated to obtain the updated multi-dimensional increment. The candidate irrigation scheme to be processed is updated based on the updated multi-dimensional increment to obtain the updated candidate irrigation scheme. The obtained candidate irrigation scheme after the update is determined as the candidate irrigation scheme to be processed in the next round, and the updated multi-dimensional increment is determined as the multi-dimensional increment to be processed in the next round.

In some embodiments, updating the multi-dimensional increment to be processed may be realized by updating an increment element to be processed. The increment element is an element of each dimension of the multi-dimensional increment, and the multi-dimensional increment may include a plurality of increment elements. There may be a correspondence between each greenspace and each increment element in the candidate irrigation scheme to be processed. The increment element may be used to represent the adjustment range of the irrigation water amount for the corresponding greenspace.

In some embodiments, the increment element to be processed may be updated based on current loss in the previous round, and the updated increment element is used as the increment element to be processed of the next round. The current loss in the previous round may be determined based on a difference between the candidate irrigation water amount elements obtained in the previous round and the historical optimal candidate irrigation parameters.

Exemplarily, after the k+1 round of iteration, the updated increment element may be calculated through the following formula (1): v _(id) ^(k+1) =ωv _(id) ^(k) +c ₁ r ₁((p _(id,pbest) ^(k) −X _(id) ^(k+1))+c ₂ r ₂((p _(d,gbest) ^(k) −X _(id) ^(k))  (1), where i denotes the number of the candidate irrigation scheme, i≤N, d denotes the number of the greenspace, d≤D. k denotes the number of iteration rounds, k≥0. v_(id) ^(k) denotes the increment element to be processed after the k^(th) iteration of the i^(th) candidate irrigation scheme. X_(id) ^(k) denotes the i^(th) candidate irrigation scheme obtained after the k^(th) iteration. co denotes the inertia weight constant. c₁ denotes an individual learning factor, c₂ denotes a group learning factor. r₁ and r₂ are arbitrary values within the interval [0,1] to increase the randomness of the search. After the k^(th) round of iteration, p_(id,pbest) ^(k) is a value of the optimal solution of the i^(th) candidate irrigation scheme during the previous iterations in the d^(th) greenspace. The optimal solution at this time may refer to after the k^(th) round of iteration, when the growth promotion value of a candidate irrigation scheme is the maximum value among the plurality of growth promotion values corresponding to the previous iterations, the irrigation water amount collection of the each greenspace corresponding to the candidate irrigation scheme (i.e., an individual historical optimal solution). p_(d,gbest) ^(k) is a value of the optimal solution of all N candidate irrigation schemes in the d^(th) greenspace after the kth round of iteration. The optimal solution at this time may refer to after the k^(th) round of iteration, among the aforementioned plurality of candidate irrigation schemes with the greatest growth promotion value in the previous iterations, the irrigation water amount collection (i.e., the group historical optimal solution) of the each greenspace corresponding to the candidate irrigation scheme with the largest growth promotion value.

The inertia weight constant ω, the individual learning factor c₁, the group learning factor c₂, and the arbitrary values r₁ and r₂ may be system default value, experience values, artificial preset values, etc., or any combination thereof, which are set according to actual requirements.

In some embodiments, the maximum absolute value of the increment element in each iteration may be v_(max), i.e., denoting the maximum adjustment range of irrigation water amount for each greenspace. In the k+1 round of iteration, the multi-dimensional increment V_(i) formed by the adjustment range of irrigation water amount for the each greenspace may be expressed as (v_(i1), v_(i2), . . . , v_(iD)). The vectors of multi-dimensional increments corresponding to N candidate irrigation schemes may be denoted as ((v₁₁, v₁₂, . . . , v_(1D)), (v₂₁, v₂₂, . . . , v_(2D)), . . . , (v_(N1), v_(N2), . . . , v_(ND))) The value of any increment element in the vector may be negative, but the absolute value is not greater than v_(max).

In some embodiments, each candidate irrigation scheme to be processed may be updated based on increment element in the updated multi-dimensional increment. Exemplarily, after the k+1 round of iteration, the updated candidate irrigation scheme may be calculated through the following formula (2): X _(id) ^(k+1) =X _(id) ^(k) +v _(id) ^(k+1)  (2).

For example, after the first round of iteration, the updated candidate irrigation scheme may be calculated through the following formula (3): X _(i) ¹=(X _(i1) ¹ ,X _(i2) ¹ , . . . ,X _(iD) ¹)=(X _(i1) ⁰ +v _(i1) ¹ ,X _(i2) ⁰ +v _(i2) ¹ , . . . ,X _(iD) ⁰ +v _(iD) ¹)  (3), the vector representation corresponding to the N updated candidate irrigation schemes may be calculated through the following formula (4): (X ₁ ¹ ,X ₂ ¹ , . . . ,X _(N) ¹)=((X ₁₁ ¹ ,X ₁₂ ¹ , . . . ,X _(1D) ¹),(X ₂₁ ¹ ,X ₂₂ ¹ , . . . ,X _(2D) ¹), . . . ,(X _(N1) ¹ ,X _(N2) ¹ , . . . ,X _(ND) ¹))=((X ₁₁ ⁰ +v ₁₁ ¹ ,X ₁₂ ⁰ +v ₁₂ ¹ , . . . ,X _(1D) ⁰ +v _(1D) ¹),(X ₂₁ ⁰ +v ₂₁ ¹ ,X ₂₂ ⁰ +v ₂₂ ¹ , . . . ,X _(2D) ⁰ +v _(2D) ¹), . . . ,(X _(N1) ⁰ +V _(N1) ¹ ,X _(i2) ⁰ +V _(N2) ¹ , . . . ,X _(ND) ⁰ +V _(ND) ¹))  (4).

In some embodiments, in each round of iterative updation of the candidate irrigation scheme, the total irrigation water amount Q of all greenspaces (i.e., the sum of the vector values of all dimensions) may have restriction: Q=Σ(X _(id))=(X _(i1) +X _(i2) +X _(i3) , . . . ,+X _(iD))≤S, where S denotes the preset total amount of the irrigation.

In some embodiments, if after an iteration, the value of the total irrigation water amount Q corresponding to the candidate irrigation parameters in the candidate irrigation scheme is greater than S, the irrigation water amount of the each greenspace in the candidate irrigation scheme may be reduced according to a ratio (S/Q). For example, after the fourth iteration, the total irrigation water amount corresponding to the ninth candidate irrigation scheme X₉ ⁴=(X₉₁ ⁴,X₉₂ ⁴, . . . , X_(9D) ⁴) is: Q ⁴ =X ₉₁ ⁴ +X ₉₂ ⁴ +X ₉₃ ⁴ , . . . ,X _(9D) ⁴ >S, and the X₉ ⁴ is reduced to: X ₉ ⁴=((S/Q ⁴)X ₉₁ ⁴,(S/Q ⁴)X ₉₂ ⁴, . . . ,(S/Q ⁴)X _(9D) ⁴).

In some embodiments, the candidate irrigation scheme may be iteratively updated through the above preset algorithms until satisfying the preset conditions, and the iterative updation ends. The preset condition may be that the preset value is reached, or the ratio of the growth promotion value obtained by algorithms to the preset theoretical maximum growth promotion value is greater than the threshold.

The plurality of candidate irrigation schemes after iteratively updating converge to a target irrigation scheme. The target irrigation scheme includes a set of target irrigation parameters for irrigating the each greenspace within the first future time period. At this time, the growth promotion value corresponding to the target irrigation scheme should be the maximum value of the growth promotion values corresponding to the plurality of candidate irrigation schemes updated in previous iterative updations.

Some embodiments of the present specification may continuously update the plurality of candidate irrigation schemes through a way of iteration, and continuously optimize the candidate irrigation schemes. In this way, the target irrigation scheme with the greatest growth promotion value is determined, and the greenspace can further achieve the best growth condition while saving irrigation water.

FIG. 9 is another exemplary flowchart for determining target irrigation parameters according to some embodiments of the present disclosure. As shown in FIG. 9 , a process 900 may include the following steps.

Step 910, the urban management platform obtains the preset total amount of irrigation in the target area within the first future time period.

Step 920, the urban management platform determines the plurality of candidate irrigation schemes of the plurality of greenspaces based on the preset total amount of irrigation and the first growth information corresponding to each greenspace, and each candidate irrigation scheme includes a set of candidate irrigation parameters for irrigation of each green land.

Step 930, the urban management platform determines the target environment information of the each greenspace within the second future time period.

The target environment information may refer to the environment information within the second future time period. Similar to the historical environment information, the target environment information may include a rainfall, air temperature, humidity, light intensity, wind power, etc. of the area where the greenspace is located within the second future time period. The urban management platform may obtain the target environment information through the sensor network platform.

Step 940, for the each candidate irrigation scheme, after irrigating the plurality of greenspaces based on the candidate irrigation scheme, the urban management platform determines the second growth information of the each greenspace within the second future time period through the growth condition prediction model based on the candidate irrigation scheme, the target environment information, and the first growth information.

For the each candidate irrigation scheme, the irrigation parameters, target environment information, and first growth information corresponding to the candidate irrigation scheme of a greenspace may be input into the growth condition prediction model, and the output of the growth condition prediction model may be the second growth information of the greenspace.

Step 950, the urban management platform determines the growth promotion value corresponding to the candidate irrigation scheme based on the second growth information of each greenspace.

Step 960, the urban management platform determines the target irrigation scheme of the plurality of greenspaces based on the growth promotion value corresponding to the each candidate irrigation scheme.

The urban management platform may determine the candidate irrigation scheme corresponding to a maximum growth promotion value as the target irrigation scheme.

In some embodiments of the present disclosure, the growth condition prediction model is configured to compare the plurality of candidate irrigation schemes, determine a candidate irrigation scheme with more growth promotion value as the target irrigation scheme from the plurality of candidate irrigation schemes by considering from a next future time period in a longer-term. Under the condition of ensuring the normal growth of the greenspace, more scientific target irrigation parameters may be determined to avoid waste of resources.
